Definition and Basic Principles The three-directional expansion indicator is mainly used to monitor the expansion of large equipment such as boilers during the heating process. It can simultaneously measure the expansion amounts of the equipment in three directions (usually X, Y, and Z axis directions). The principle is based on the measurement of mechanical displacement. When the equipment expands due to heating, the measuring components of the expansion indicator will undergo displacement along with the expansion of the equipment, and thus the expansion values can be read on the scale and the indicator needle. II. Structural Composition Indicator Pointer: This component directly contacts the equipment and senses the expansion displacement. It is generally made of stainless steel and has excellent thermal stability and mechanical strength, enabling it to accurately move along with the expansion of the equipment. Dial: The dial is the component that displays the expansion quantity. It is marked with precise scales, used for reading the expansion quantity of the equipment in various directions. The accuracy of the scale depends on different application scenarios and measurement requirements, and can generally be precise to the millimeter level. Connector: It is convenient for the indicator pointer and the pipeline to connect. It is usually connected by pipes and branch pipes. The branch pipe and the connector are connected. Note that the connector should be installed vertically or horizontally.III. Installation Key Points Position Selection: It should be installed at the key position where the equipment is likely to undergo significant expansion, such as the heated surface tubes of the boiler, the steam drum, etc. At the same time, the installation position should be convenient for observation and reading, generally installed on the outer surface of the equipment.For example, when installing on the steam drum of a boiler, the straight cylindrical section of the steam drum should be selected, avoiding installation in areas with complex pipeline connections or where it is difficult for people to approach.
